Had a very freaky dream that my stepfather killed me?

well last night i had an extremely scary and realistic dream where my stepfather killed me (don't remember how) and i died and became a ghost. keep in mind that my stepfather is a jerk and i am not in favor of him but i know he is not an evil person and would never kill someone. anyway so i become a ghost and then i see a group of people and i recognize them as my real-life friends, and they are all dead. then i remember seeing my entire family crying except my stepfather who is just sitting there with an eerie frown. lastly i remember my friends telling me through tears that there was a 'death game' and you could play it to be restored to life...then i woke up sweating. i know it sounds very unrealistic but it kinda freaked me out...also anyone else have some scary dreams of their own to share?
